A Better CO-OP

The game at its heart is a RPG. If I was your friend I dont want to watch you play a story based game where I dont get to make any of the decisions. Also the game shooter mechanics would need to be stripped down to how they are in MP. Which is very limited.

Why does every game need CO-OP, MP, and any story driven material ripped out of it? I really wish companies would leave RPG's alone.

That would impact the reason for the Multiplayer: getting sales of Andromeda Points for Gambling boxes.  

Co-Op in ME:A and DA:I was not designed to round out the game with something gamers wanted, it was designed to be an additional revenue stream. 

Co-Op through the campaign is something many people have asked for, and would be a lot of fun during Combat. But, that's where the Multiplayer comes in except that you need to grind or pay to progress and can't just build a character and go.
